Quantification of High-dimensional Non-Gaussianities and Its Implication to Fisher Analysis in Cosmology [PDF]

The Astrophysical Journal, 2023
It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that

Twenty-First-Century Statistical and Computational Challenges in Astrophysics [PDF]

Annual Review of Statistics and Its Application, 2020
Modern astronomy has been rapidly increasing our ability to see deeper into the Universe, acquiring enormous samples of cosmic populations. Gaining astrophysical insights from these data sets requires a wide range of sophisticated statistical and machine

Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validation

Diversity and Distributions: A journal of biological invasions and biodiversity, 2023
Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what ...

Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies

The Astrophysical Journal, 2023
Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining the mechanism that counterintuitively heats coronae to temperatures that are orders of magnitude hotter than the ...

A New Approach to Astronomical Data Analysis Based on Multiple Variables

Advances in Astronomy, Volume 2023, Issue 1, 2023., 2023
Data analysis for a sample of celestial bodies generally is preceded by the completeness test in order to verify whether the sample objects are proper representatives of the corresponding part of the universe. A data set following a multivariate, continuous, uniform distribution is said to be “complete in space.” This paper introduces a new approach to

Analytical guidelines to increase the value of community science data: An example using eBird data to estimate species distributions

Diversity and Distributions: A journal of biological invasions and biodiversity, 2021
Ecological data collected by the general public are valuable for addressing a wide range of ecological research and conservation planning, and there has been a rapid increase in the scope and volume of data available.

Characterizing the Conditional Galaxy Property Distribution Using Gaussian Mixture Models

The Astrophysical Journal, 2023
Line-intensity mapping (LIM) is a promising technique to constrain the global distribution of galaxy properties. To combine LIM experiments probing different tracers with traditional galaxy surveys and fully exploit the scientific potential of these ...

Parton distributions from high-precision collider data [PDF]

The European Physical Journal C, 2017
We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test.
